UPPER-SHAPING MACHINE.

To all fio/0m t may concern.'

Be it known that I, MATTHIAS BROCK, a citizen of the United States, residing at Boston, in the county of Suffolk and ,State of Massachusetts, have invented certain Improvements in Upper-Shaping Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to machinesI for shaping upper materials andl is herein shown as embodied in a machine which is adapted for molding the heel portions of shoe uppers, the characteristic features of the type of machine illustrated being more fully described in prior United States Letters Patent Nos. 1,197,437 and 1,197 ,439, granted Sept. 5, 1916 upon applications filed by me.

One object of this invention is to produce more effective shaping and better distribution of the fullness in the margin of an upper that is forced inwardly over a convex end portion of a shoe last or form by relative movement between the form and margin engaging means. The most satisfactory7 means for forming the margin of the upper into an inwardly turned sole attaching flange comprises end embracing wipers which gather and wipe the margin inwardly over the tread face of the form or last. The inturned margin resolves itself vintov plaits or folds to take care Vof-the fullness caused by bending it into a smaller circle or cur vature. A feature of this invention consists in a novel construction and arrangement of means to coperate with flange shaping means to distribute the fullness so that large plaits are avoided. This is effected in the margin of .the upper `against the edge of the wipers as they advance and close so as to restrainV the marginal stock from doubling Von itself to produce folds,.the illustrative construction comprising` means to engage the inner side of the upstanding margin of the upper arounr the shoe end.

drawn down between the wiper edges and the holding means to produce the inturned flange. An effective embodiment of this feature of the invention consists in the combination with a form and means to bend the margin of the work inwardly over the form, of margin holding means guided on the form. The holding means may be advantageously spring held in its operative position and movable by force transmitted from the wipers.

Another feature of the invention consists in the provision of means for preventing` displacement of the flange by the margin holdingmeans, for example, during the return movement of the wipers or other bending means over the fla-nge. In the illustrative machine the wipers are reciprocated repeatedly and the margin holding means is organized to operate during the first closing movement of the wipers and to remain inoperative during subsequent reciprocations of the wipers over the same piece of work.

A further feature of the invention consists in a novel construction and arrangement of upper shaping means designed to prevent displacement of the upper in the upper shaping operation.` The illustrative construction embodying this feature comprises inside margin holding means which is arranged to project beyond the edge of the bottoni face of the inside form lin position substantially to engage the upper stock in the position which it occupies before the shaping operation begins. The margin of the` upper is thus gripped between the holding means and the wipers at the beginning of the upper shaping operation, in time to restrain the upper as a whole from tipping movement relatively to the form in such manner as to depress unduly the portions at the sides of the form including. for example, the wings of the counter.

In the operation of a machine constructed in accordance with the preferred embodiment of this invention there is a marked tendency to reduce the extent of fullness to be distributed in the overwiped margin. This is due to the stretching action on the margin of the stock widthwise from the edge of the form or last and its consequent lengthwise contraction as it is drawn out and turned down, so that fewer plaits are re- 1n addition to the foregoing the invention includes various features of construction and combinations of parts designed with a view to the application of the invention to upper shaping mechanisms of the type shown in said prior patents and particularly to automatic machines embodying the invention set forth in said Patent 1,197,439. These features will all be more fully understood from the following description with the aid of accompanying drawings of an illustrative machine embodying the invention, and will then be particularly pointed out in the claims.

Figure 1 of the drawings is a side elevation of a machine embodying the present invention;

Fig. 2 is a perspective view dealing particularly with parts of the machine added by this invention;

Fig. 3 is a perspective view showing the upper shaping devices at the beginning of their action on an npstanding margin of .an

upper which vis to be shaped into an in-` turned upper atta ching flange over the tread face of a heel form;

F ig. 6 is a similar view after the wipers have completed a flange forming movement inwardly over the work, forcing the margin holding means ahead of them;

Fig. 7 is a vertical longitudinal section through the margin holding means and the upper part of the form.

Figs. 8 and 9 show modifications.

As pointed out in the said patents, the machine comprises a plurality of duplicate units built into one machine so that a plurality of shoe uppers may be in process the same time. 1t will sufiice to describe this invention in connection with one of said units.

The upper shaping mechanism comprises a last or form 2, herein shown as a metal heel form of more pronounced curvatures than the corresponding last; a multi-part forni embracing mold 4 shown in dotted lines in Fig. 1 and backwardly into which the form carries the work; and heel embracing wipers shown best in Figs. 5 and 6 and comprising advancing and closing endv members 5 and side members 6 that have a closing movement without advancing.

The machine is power driven, being controlled by a foot treadle 10 connected with a clutch 12 on a driving shaft 13. This shaft is geared to the cam shaft 14 which operates through a lever 15, a rod 16 and form carrier 18 to draw the form back into the mold; through a lever' 20 and toggle 22 to close the mold for clamping the upper about the side faces of the form; through a lever and rod 25 to close the wiper controlling clutch and set the wipers to reciprocating; Vand through a lever 26, toggle 27 and rods 30, 32 and spring 33 to raise the form yieldingly against the wipers. These movements having been effected, the cam shaft comes automatically to rest while the wipers, which are driven from a constantly running pulley 35, are continued in recipro cation to shape the inturned iiange of the upper by repeated rubbing movements forth and back over the flange.

rFhe mechanism and organization thus far described is like that more fully shown and .described in said prior patents and the present invention is not concerned with the details thereof.

The top face of the form 2 is dove-tailed to provide a slideway for the foot piece 40 of the margin holding means. In the foot piece is guided the side rod or stem 42 to the head of which are secured toggle mem- Y bers or links 44. These are pivotally connected to the front. or free ends of the margin holding members 45 which are pivotally connected together and to the foot piece 40 as shown in Fig. 7 and are shaped to conform substantially to the curvature of the convex rear edge of the form 2. The margin holding` members are maintained normally in the outspread position shown in Figs. 2, 3 and 5 by the assistance of light leaf springs 46 secured to the foot piece 40 and extending between the free ends of the members 45.

The margin holding means is maintained in the position shown in the slideway on form 2 by a presser 5() which is the upper arm of a bell-crank lever fulcrumed in the form carrier 1S and having a horizontal arm 52 pressed down upon by a spring 54, Fig. c) ing members to be pressed forwardly and swung inwardly against a substantial yielding resistance as the wipers advance and close. Y

The construction and organization thus far described is such that the margin holding members stand in the position shown in Figs. 1, 2 and 3 when the form 2 is in work receiving position. 'Art such time they may serve as a Vheight gage to guide the operator in positioning the work at the right elevation to provide the desired width of inturned iiangeon the upper. rhe margin holding means moves backwardly with the form as the latter carries the work into the mold.y see Fig. 5. As the wipers advancethe members 45 hold the margin in upstanding position around the convex portion of theV edge of The spring 54 allows the margin hold` folds or plaits and require the margin to be stripped under tension from between said members 45 and the wipers. The spring 54 is preferably strongenough to prevent the passage of any folds or doubled portions of the stock between the members 45 and the wiper edges, with theresult that the fullness is ironed out andy the margin stretched widthwise and therefore contracted length-v wise. As the advance of the wipers proceeds the condition shown in Fig. 6 is reached where the margin has been pulled down entirely under the wipers.

I It is desirable that the members 45 shall not follow the wipers in their backward stroke from the position shown in Fig. 6 because there would be a tendency to disturb the wiped down flange. To control the margin holding means in this respect the arm 52 in the construction shown in Figs. 1 and 2 carries a spring pin having a beveled outer end which engages under a' stationar roll 56 when the form carrier 18 thrusts the form back into the mold. Vhen the wipers advance and move the members-45 and the presser 50 forward the arm 52 is raised against resistanceof spring 54, the beveled end of the spring pin 55 permitting it to clear the roll 56 and the spring back of the pin projecting theA pin into position to rest upon the roll 56, which thereafter will hold the presser from returning the margin holding means to starting position. This not only relieves the members 45 vfrom pressure tending to move them reversely lengthwise of the form, but also insures against their return movement laterally of the form in such manner as to displace the wipededown flange of the upper, the tension of the light springs being insufficient to swing these members outwardly to the edge of the form as the wipers are backed-away. The wipers may then reciprocate repeatedly over the work while the margin holding means re mains idle substantially in the position shown in Fig. 6. v

In the illustrated machine the wipers are reciprocated repeatedly. ator, after having dealt with the work on the other units ofthe machine, is ready to remove the upper from the form 2, he starts the cam shaft by depressing' the treadle 10 and the several parts are restored to starting position, Fig. 1, the shoe being released with the heel portion of its upper shaped to'fit a last and its margin formed into an inturned sole attaching flange. As the form carrier moves out to shoe discharging position, Fig. 1, the spring pin 55 is drawn off from the yadvance over said next upper.

lVhen the open roll 56, thereby freeing the spring 54 to operate for returning the margin holding means to work gaging position, maintaining it there during the application of the next shoe upper and in margin holding relation to the wipers during their flange forming It will be noted that the pin 55 is released from the roll 56 before the form 2 reaches its outermost position. This release and the consequent actuation of the margin holding means rearwardly over the form 2 by the spring 54 is utilized to overcome adhesion of the upper to the form and facilitate removal of the work from the form by the operator.

In Figs. 8 and 9 is shown a modification characterized by a new position, and combinative effect, of the margin holding means relative to other parts operating on the work, and by an alternative controlling mechanism for the margin holding means. In this embodiment of the invention the margin holding means is so constructed and arranged relatively to a form 2 having a vertically convex rear face that in the normal work receiving position of the parts the stock engaging outer edge face of said means is substantially in vertical alinement with the outermost part of said convex face of the form around the curved rear end of the form.

It will be noted by reference to Fig. 1 that in theeeonstruction there shown the margin holding means is arranged to have a work receiving position substantially at the edge of the heel seat face of the form. This is the right condition for molding uppers that have been cut to shape at the back seam, that is, are formed with a pocket as shown for example in application United States Letters Patent No. 1,238,856, granted Sept. 4, 1917, on application of Thomas F. iVhelan.

In dealing with work in which the upper has not been cut to approximate the shape of the rear end of a convexly faced mold or in which a straight or unmolded counter is included with the uppe'r materials, there is a tendency for the flange bending wipers 5 to tip the upper about the rear end face of the form 2 and thus move the stock downward with relation to the front portion of the mold. This throws the wings of the counter down and provides insufficient width of margin to bend in for producing the solo attaching fiange. lt also tends to produce excess fullness at the top of the heel` which causes the shoe to fit imperfeetly. These difficulties are overcome by the construction and a rangement shown in Figs. 8 and 9 for presenting a margin holding face on members 45 in eoperative relation with the margin bending wiper members in a position `in which said face is substantially alined vertically with the extreme rear part of the form 2. As thus arranged the membersl 45 and the wipers grip the upstanding mar- In Fig. 8 the ilatching meanso'll Fig. l in Y cluding the spring pin in the'end ot arm. 52 is replaced by a pivoted spring pressed latch 60 which is tipped toward the right by said arm asthe arm travels in that direction with Athe form carrier 18, and when the armis lifted, by the forward displacement of the margin holding means and its presser 50, the end of arm 5irides up the' edge of the latch until Yit seats in the recessed portion ot the latch which holds it up and prevents the return oirc the arm andv the margin holding members #t5 by spring 54 when the wipers are retracted and during the successive. subsequent i'ecipi'ocations of the wipers until the form carrier is again moved toward shoe discharging position when the end of arm 52 is drawn Jforwardly out oi' the recessed portion of the latch. The recessed portion of the latch is secured on a holder (3Q which is mounted on a pivot 6a and controlled by a spring 66,V said recessed portion being adjustable upwardly or downwardly on; its

holder to conform to diii'erent limits oi movement of the arm' 52 depending upon the extent of the movement imparted by the wipers to the margin holding means.

This invention has been shown and described for explanatory purposes as an improvement applied to a machine used for shaping the heel portions of: upper materials, including the vheel stiiiener and lining, preparatory to lasting. it isV to be understood, of course, that the invention .may be applied to any machines for forming sole attaching flanges on upper materials, such as toe shap ing machines, stiifener shaping machines, and toe and heel lasting machines, and the term upper7 is' used herein in a comprehensive senseI with a view to such various uses of the invention'. f
